Limiting factors of photosynthesis

This resource is designed to help students to describe and explain the patterns shown in graphs. It uses the context of rates of photosynthesis for the graphs.

There are two tasks - in the first students are asked to describe the graph and in the second they are asked to explain the graph. This gives a perfect opportunity to show students the difference between the command words and the answers that they should give. Annotated graphs with the answer are provided.
